Expose Full Repository Cleanup API

Context

In the context of the benchmarks, we are likely to want to reset the repository several times typically because we want to re-do the import from the beginning with different parameters.

The idea is to avoid having to go through a devops task so that:

• we can be fast
• we avoid overwhelming the NCO team for no good reason

Scope

• reset MongoDB
• reset ES index
• trigger the Repository Init event ? (content template)
• cleanup audit ?
